Color Coding Method in Augment Reality Based on Enhanced Visual Depth Perception

Augmented view is a pace composed of virtual and real information superimposed in an augmented reality system. Color, as an important visual coding channel in augmented view, can help users build depth perception. This study focuses on the effect of color coding on depth perception in the augmented view. In this study, blue was used as the basic color of the experiment. The user behavior experiment used cluster analysis and qualitative analysis to obtain two design strategies for color depth perception. In addition, based on the above strategies, the corresponding relationship between the perceived quantity of blue and the physical quantity is obtained, and the minimum value of the just-noticeable difference (JND) is determined to be 6%. Based on these results, this study proposes a color ordering depth coding method based on a depth perception strategy, which provides a reference value for enhancing color visualization of virtual information depth in the visual field.
